SANTARY CLOSE` CONNECTION.

Application filed March 8, 1921,

To all whom t may concern:

Be it known that l, MICHAEL O LEARY, of Cleveland, in the county of Cuyahoga, in the State of Ohio, have invented new and useful Improvements in Sanitary Closet Connections, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to certain improvements in floor connection for closet-bowls and soil-pipes of the class set forth in my Patent #1,206,580 issued November 28, 1916, the main object being to simplify the means for preventing the leakage of gas or moist-ure at the joint between the horn of the bowl and soil-pipe, and at the same time to facilitate the assembly of the bowl in proper relation to the soil-pipe.

In other words, I have sought to render the joint water and gas pipes by means of a single packing-ring constructed in such manner that the mere act of assembling the parts one within the other will automatically tighten the packing against both parts throughout the peripheries thereof.

Other objects and uses relating to specific parts of the packing-ring will be brought out in the following description.

In the drawings:

Figure l is a vertical sectional view of portions of a soil-pipe and closet-bowl with my improved packing-ring in operative position.

Figure Q is a. perspective view of the detached packing ring.

The soil pipe as 1- flanged at its upper end for support upon the floor Q-- to receive the lower end or horn E3- of a closet-bowl -4- or similar fixture, which in turn is provided with a base-flange -5- of considerably greater diameter than that of the soil-pipe -land adapted to rest upon the upper face of the floor 2 around the upper end of the soil-pipe where it is secured in place by suitable fastening means as screws --6-.

The external diameter of the horn -3- is appreciably less than the internal diameter of the soil-pipe -lto allow those parts to be easily assembled one within the other, and at the saine time to form sufficient space for the reception of a packing-ring T.

rl`his packing-ring is preferably made of thin sheet copper or equivalent material having more or less resiliency and flexibility to enable it to tit tightly against the ad- Selal No. 450,597

`iacent walls of the horn -3- and soil-pipe --l-, as will be hereinafter more fully eX- plained.

The main body of the packing-ring -7- is made in the form of a truncated cone arranged in an inverted position within the upper end of the soil-pipe -land having its base provided with an out-turn annular flange -S- and its lower end provided with an outwardly and upwardly deflected annular flange -9-.

The base flange --8- is of considerably larger diameter than the inner diameter of the soil-pipe --land is adapted to rest upon the upper end thereof to support the packing-ring in operative position against` downwardly displacement, the inner diameter of the base of said ring being of considerably greater diameter than the external diameter of the horn -3- to enable the latter to readily enter the ring when the parts are being assembled.

The inner diameter of the inner end of the packing-ring -7- is normally slightly less than the externa-l diameter of the horn 3- so that when the horn is inserted therethrough, the inner end of the packing-ring will be slightly expanded and thereby caused to fit snugly against the periphery of the horn throughout its circumference.

The flange Q- is formed integral with the main body of the packing-ring -7- and flares upwardly and outwardly from the lower or smaller end of said ring, the free edge of the flange being of slightly greater diameter than the interior diameter of the soil-pipe 1 so that when the ring 7lis inserted into the soil-pipe, the flange 9 will be slightly contracted against its own resiliency and thereby caused to fit tightly or snugly against the inner walls of the soil-pipe to assure a liquid and gas tight` joint, it being understood that this engagement of the free edge of the spring flange --9- with the walls of the soil-pipe -lalso produces inward pressure upon the lower end of the ring -7- to cause the latter to additionally bind or clos-ely hug the periphery of the horn -3-.

In assembling the parts, the soil-pipe is first placed in operative position relatively to the floor -2- after which the packingring -7- is placed'in operative position upon the upper end of the soil-pipe with its ilange -8- resting against the upper end of said pipe and the remaining portions extending thereinto. rIhe bowl 4* is then placed in operative position upon the floor so that its horn -3- will extend down through the ring -7 with a wedging action against the inner face of the smaller end ot the ring, thereby slightly expanding the latterl and causing the free edge of the flange -9- to be tightly iinpinged against the inner face of the soil-pipe lthus 'forming liquid and gastight joints between the lower end oit the ring and horn -3, and another gas tight joint between the tree edge of the flange -9- and soil-pipe -1-.

" The upward and outward filare of the iange S3- permits the sinaller end of the packing-ring -7 to be wedged tightly downwardly and inwardly against the inner face of the soil-pipe -l until lirnited by the' engagement o the Iiange -S with the upper end of the soil-pipe. lVhen the ring -7- is thus inserted in the soil-pipe, .the interior diameter of the smaller end thereof will be Somewhat less than the interior diameter of the horn 3m so that when the horn is inserted therethrough, it will slightly expand the inner end ol the ring and Cause' it to lit closely against the periphery of the horn while the iange --9- will be tightly iinpinged against the inner surface of the soil-pipe -ltending to hold the lower end of the ring against the horn.' I

Vhat I claim is:

l. In a floor connection for closet-bowls and soil-pipes, the combination of a soilpipe, a closet-bowl having a horn inserted into the soil-pipe, and a packing-ring of sheet nietal having its niain body tapered from one end toward its opposite end and inserted in the space between the horn and soil-pipe with its smaller end in olose engagement with the peripheryv of the horn, said lower end having an out-turned annular flange engaging the inner face of the soil-pipe. y

2. In a Hoor connection for closet bowls and soil pipes, the Combination of a soil pipe extending through an opening in the floor and having its upper end 'flanged outwardly to reet upon the upper surface of the Hoor, a closet bowl having its base resting on the floor over and around the outer end of the soil pipe and provided with ahorn extending` eoaxially into the soil pipe in spaced relation thereto, and a sheet metal packing ring extended into the space between the horn and soil pipe and having its outer end resting upon the outer end of the soil pipe and its inner lend tightly fitted against the periphery of the horn, and an annular portion thereof7 tightly fitted against the inner face of the soil pipe.

In witness whereof I have hereunto set my hand this lst day of March 1921.
